Have you purchased a new RV recently and notice a toxic odor that emits from the interior every time you open the door? Or do you already own an RV that causes your eyes to water, nose to sting and gives you a headache every time you go inside? Generally, the odors you smell and the reactions you are experiencing are a result of various amounts of formaldehyde and other chemicals found in the particle board, glue and other synthetic materials that are used to construct your RV. Even though there are some regulations regarding the use of these chemicals in certain building materials, the regulations do not totally prohibit the use of toxic chemicals in the use of everyday building items.
